I have been in your shoes before and actually bought a deck over 8 wide and long(33 ft)(6 sleds), 7 wide and long(29 ft)(4 sleds- can get 5 in if you can get sleds to sit side by side opposite of each other with 5th in V) and currently a 2nd 8 wide sport/auto(wider axles that sits between the center of side walls. My previous was 26 ft(4/5 sleds) and my current is 28'(4/5 sleds) My opinion is each one has their benefits along with cons. Nothing wrong with each. The deck over had the most cons and the one I would stay away from if possible. The 7 wide is a great trailer but you actually need to go longer to just fit a certain number of sleds you need. My issue is wasted space in a stagger fashion along with limited usable trailer hauling capabilities due to narrow interior width. Great for a half tonner tow rig to pull in front. The sport model I now have is about as ideal a trailer you can get for its wider range of hauling capabilites. You can haul a car, small suv, jeep, utv, etc. I recommend this type of trailer as it offers the most pros for its hauling capabilities and space. If you're looking to have a snug fit for 5 sleds with 4 most of the time, I recommend a 26 ft which I used to have. I upgraded because of trailer age and 28' was all the dealer had at the time so I went with it and love it which has a tad more room than the 26 ft. Believe it or not, I am yet again trailer shopping. This time I am stepping up to the gooseneck version for an even more range of use I am looking to achieve. Good luck with your decision.
